No mapping found for HTTP request with URI [/Spring3MVC2/contacts.html] in DispatcherServlet with name 'spring' error on 7.1.1

[mschwery]

I am trying to run the http://viralpatel.net/blogs/spring-3-mvc-handling-forms/ example

and getting the  No mapping found for HTTP request with URI [/Spring3MVC2/contacts.html] in DispatcherServlet with name 'spring' error on 7.1.1.

Has anyone got any ideas on how to get this working.
